Democritus- He called an uncutable particle an atom
Believed atoms were always in motion
Believed matter was imperishable.
Dalton- Elements combine based on mass to form different compounds
Hydrogen + Oxygen = Water
Elements combine in specific proportions because they are made up of individual atoms
Five main points of Dalton's Atomic Theory
Elements are made of tiny particles called atoms.
All atoms of a given element are identical.
The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative weights.
Atoms of one element can combine with atoms of other elements to form compounds; a given compound always has the same relative numbers of types of atoms.
Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.
